POWER-TRANSM ITTER.

SPECIFICATION forming part of Letters Patent No. 485,952, dated November8, 1892.

Application filed June 25, 1892. Serial No. 437,964. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM LARSON and OLE GUNDERSON, both of LakeMills, in the county of iVinnebago and State of Iowa, have invented anew and Improved Power- Transmitter, of which the following is a full,clear, and exact description.

The object of the invention is to provide a new and improvedpower-transmitter, which 1s simple and durable in construction, veryeffective in operation, and more especially des gned for converting thereciprocating motion of a wind mill-rod into a rotary motion.

The invention consists in certain parts and details and combinations ofthe same, as will be fully described hereinafter, and then pointed outin the claim.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, m which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is an end elevation of the improvement. Fig. 2 is a sideelevation of the same, and Fig. 3 is a broken sectional side elevationof one of the ratchet-wheels and its pawl.

The rod A of the wind-mill or other machineryhasthe usual reciprocatingmotion and is connected to a head B, provided with two arms 0 and C,which, with the head 13, form a link for connecting the arms D and Dwith each other. The arms D and D are fulcrumed loosely on shafts E andE, respectively, mounted to turn in suitable bearings arranged in aframe F of any approved construction. On the pivoted arms D and D arefulcrumed the spring-pressed pawls F and F respectively, engagingratchet-wheels G and G, respectively, secured on the shafts E and E,respectively. The teeth of the ratchet-wheels G and G extend in oppositedirections, as will be readily understood by reference to Fig. 2, andthe pawls F and F are correspondingly arranged upward and downward, sothat When the arms D and D swing simultaneously upward the pawl Fengages its ratchet-wheel G and turns the same, while at the same timethe other pawl F glides over the back of the teeth of the other ratchetwheel G. On the downward motion of the arms D and D the spring-pressedpawl F glides over the teeth of its ratchet-wheel G,

while the other pawl F engages its ratchetwheel G and turns the same.

The shafts E and E are connected with each other by gear-wheels H and H,respectively, and on the shaft E is secured a large gear-wheel I, inmesh with a pinion J, secured on the main driving-shaft K, carrying atone end a fly-wheel L and at its other end a pulley N, connected by beltwith other machinery for transmitting the rotary motion of the shaft Kto the said machinery.

The operation is as follows: When the several parts are in the positionshown in the drawings and the rod A moves upward, then an upwardswinging motion is simultaneously given to the arms D and D, as thelatter are connected with the said rodA by the link composed of the headB and the arms 0 and C. The upward swinging motion of the arms D and Dcauses a revolving of the shaft E in the direction of the arrow at bythe action of the pawl F on the ratchet-wheel G, as above described. Themotion of the shaft E is transmitted by the gear-wheel I to the pinion Jand shaft K, so that the latter rotates in the direction of the arrow12'. During the upward stroke of the arms D and D the spring-pressedpawl F loosely glides over the teeth of the ratchet-wheel G, so that theshaft E of the said ratchet-wheel is free to revolve in the direction ofthe arrow 0' on account of the movement given to it by thegearwheels Hand H. On the downward movement of the rod A a downward swinging motionis given simultaneously to the arms D and D, so that the shaft E isagain revolved in the direction of the arrow 1) by the action of thepawl F on the gear-wheel G. The motion of this shaft E is nowtransmitted by the gear-wheels H and H to the shaft E, which lattercontinues in its movement in the direction of the arrow a, so that alike rotary motion is given to the shaft K in the direction of the arrow1). During this downward stroke of the armsD and D the pawl Fglides overthe back of the teeth of its ratchet-wheel G, so that the movement ofthe latter and that of the shaft E is notinterfered with. It will beseen that by this arrangement a continuous rotary motion is given to theshaft K during the time the rod A is reciprocated.

It will further be seen that the device is very simple and durable inconstruction, composed of but few parts, and not liable to get out oforder. The rod A is preferably secured by set-screws in the head B, andthe arms (J and C are likewise fastened in place by set-screws, so thata ready adjustment can be made at any time between the link composed ofthe arms 0 O and the head B with the rod Aand the arms D and D.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The herein-described power-transmitter,
